What Is Urethral Fistula Repair After Phalloplasty or Metoidioplasty?
Urethral fistula repair is reconstructive surgery used to close the abnormal pathway and restore urine flow through the intended urethral channel. Before repairing the opening, it is important to determine whether a urethral stricture is present because pressure behind a narrowing can contribute to persistent leakage or fistula recurrence.
A small, well-localized fistula may be closed primarily after removing the tract and bringing healthy tissue together. More complex defects may require additional tissue. Buccal mucosa from the inside of the mouth can be used to patch or augment the urethra, and local or regional vascularized tissue can be placed over the repair to separate suture lines and improve coverage. In heavily scarred or previously repaired areas, a staged plan may be safer.
